Four attackers were shot by police and officials now say four others have been caught.

Those responsible were described by Chinese officials as "terrorists" from the far-western province of Xinjiang.

But when delegates from the restless province gathered at the annual National People's Congress it was as if the bloody rampage never happened and everyone is content in the vast, predominantly Muslim province.

Over the past year there has been an increasing number of these violent clashes reported inside Xinjiang, where many local ethnic Uighurs seek independence from China.
